I am currently using hydroquinone 4% daily and tretinoin 0.025% twice a week. I have Fitzpatrick Skin Type III. Should I continue with 0.025% and gradually increase the frequency, or would switching to 0.05% provide better results? Which option is more effective while minimizing irritation and the risk of pigmentation?
